I accidentally ate the carp after releasing it.

The tone of not eating that animal sounds superstitious, but it is right to set it free. I suggest you read Buddhist classics online. Buddhism hopes that all beings will not eat meat, because some people eat it, so it is also guilty to eat it, but if they can't, they will eat three golden meats, that's all; If you can't see or hear, don't kill for me. It is better to eat this kind of meat. Regardless of the above situation, we should repent and do something, such as chanting Buddha and vowing to return our merits to it. As for him saying you can't eat, there is also a possibility that you swear never to eat again for your health. Now you should release more, return your merits to it and make a new wish. I can't make a wish, if I can't, I can't get what I deserve, because I made a wish, and you did your work and returned to it; I hope this merit will make me disease-free. Attention; Don't eat boiled live fish because it's for you. Although you don't kill it, you only eat it. However, killing life is basically the same as killing life. Multi-release and long service life.
